I was wondering if you all also got the dota 2 invite for the survey.
They will be inviting alot more people to the beta.
So if you have signed up for the beta keep an eye out for the invite in your mailbox!

Edit:
Just filled out my survey, never played DOTA before but luckily the 5 most played Dota 1 champs section was not a required section. Still, the survey is mainly geared towards previous Dota players so I kind of doubt I'll get an invite but it never hurts to try.

I think it'll be wise of Valve to invite Dota newbies as well. I think they need to be sure it'll be accessible for new players if they want it to grow. If they just cater to the old Dota crowd, I don't think they'll succeed as much.
